INTRODUCER SHEATH Filed May 5, 1965 United States Patent 3,397,689 INTRODUCER SHEATH Vittorio Marcantonio, 9 Via Silvestro Petrini,

Chieti, Italy 1 Filed May 5, 1965, Ser. No. 453,274 Claims priority, application Italy, Mar. 4, 1965, 4,645/65 4 Claims. (Cl. 128-79) ABSTRACT OF THE DISCLOSURE An introducer sheath for assistance in mating which is provided with a base plate with an aperture into which a hollow substantially rigid sheath member with a closed end portion is rotatably secured. The sheath member has a longitudinally extending lateral opening to permit contact between the generative organs.

The present invention refers to an introducer sheath intended to act as a mating aid.

In its general form, the sheath according to the present invention consists of a generally cylindrical or tapered, hollow, sufiiciently rigid component of a plastic or rubberlike material, into which the male organ is introduced and which thus forms for it a supporting sheath to assist its introvaginal introduction and permanence.

According to another feature of the invention, this component is provided with a longitudinally extending lateral opening of appropriate length and width, to permit, across its area, a direct contact and thus eliminate the barrier to the senses formed by the thickness of the sheathing material necessary to confer to said material the required rigidity. According to an additional feature of the invention, the sheath is completed by a base plate, provided with an opening, upon which it can be rotatably secured. The base plate is provided with means by which it may be strapped to the wearers body.

An exemplary embodiment of the invention will be described in the following, reference being made to the attached drawing, in which:

FIGURE 1 shows a cross-section of an embodiment of the device according to the invention, mounted on its base plate.

FIGURE 2 is a top view of the base plate.

FIGURE 3 is a sectional detail showing a form of rotatable attachment of the sheath to said base plate.

FIGURE 4 is another possible form of rotatable attachment between sheath and base plate.

With reference to the drawing, the sheath generally indicated at 1 consists of an approximately tubular or tapered component 2 attachable to a base plate component 3. The upper end of the sheath, as viewed in FIG. 1, forms a convex, cup shaped portion 4, which may be either perforate or imperforate. The lower end 5 carries means adapted to secure the inlet opening of the component 2 to the edge of the opening 6 of the base plate 3. Any type of snap-joint connection between sheath and base plate may be adopted. However, it is obvious that any other suitable type of connection can be used, such as a threaded connection. The snap-joint connection illustrated in detail in FIG. 3 is obtained by forming said lower sheath end 5 with an inwardly projecting peripheral groove or recess 7, with the diameter of the innermost portion of said groove or recess being approximately equal to the diameter of opening 6, in order to permit the peripheral edge 6:: of the latter to snap into said groove 3,397,689 Patented Aug. 20, 1968 when sheath 2 is inserted into the opening under a slight pressure. In the alternate form shown in FIG. 4, the lowermost part of portion 5 has a peripheral thickening 5a which can be snapped into a corresponding annular groove 3 provided around opening 6.

At a distance from its cup-shaped top end 4, down to a given distance from its lower end 5, as at level 9, sheath component 2 is provided with an opening 10 occupying part of the lateral wall of the sheath component. The peripheral edges of opening 10 are conveniently rounded or otherwise smoothed, to prevent them from cutting into the flesh during use. For the same reason, the opening 10, although having a contour of optional conformation, should avoid sharp corners. Its size and general shape should be selected so as not to substantially reduce the stiffness of the sheath component 2.

The base plate 3 is either flat or slightly convex with a suitably rounded contour, and carries two slots 11 for the insertion of two straps by which the base plate can be fastened to the wearers body.

The opening 10 in the lateral wall of the sheath and the rotatable connection of the latter to the base plate, serve to obtain a direct contact area between the male and female organ to assist erection.

The use of the present sheath permits a complete contact automatically. The present sheath is just as useful in cases of vaginal restriction.

What I claim is:

1. An introducer sheath comprising a tubular body of substantial rigidity having opposite ends and including a closed convex portion at one end, said body being open at the other of the ends and having an elongated opening extending along a portion of the length of the body between said ends, a base plate adapted for being attached to the users body, said base plate having an opening therein, and means on said base plate and body for securing the same detachably and rotatably at said other end of the body with the opening in the end of the body and the opening in the base plate in registry.

2. An introducer as claimed in claim 1 wherein said means for detachably and rotatably securing the base plate and body comprises an annular peripheral enlargement on said body at said other end, said base plate having a recess for receiving the peripheral enlargement.

3. An introducer as claimed in claim 2 wherein said base plate includes an annular projection defining said recess.

4. An introducer as claimed in claim 1 wherein said means for detachably and rotatably securing the base plate and body comprises a rim portion on said body at said other end with a peripheral recess, said base plate engaging said rim portion at the peripheral recess.
